president obama said today the united states is gathering evidence in the murders of the u.s. ambassador to libya and three other americans, but he said "there is no doubt that the assault on the u.s. consulate in benghazi this past september 11 wasn't just a mob action." evidence is growing that the murder of ambassador chris ssevens was planned and targeted. in new york today the president of libya met with secretary of ofate clinton at the united nations. he said that the libyan people had lost a friend. a year ago in libya a bunch of ragtag militias overthrew the dictator moammar qaddafi and ne's one of those militias that's suspected in the attack on the americans. ttat attack was apparently the last straw for the people in benghazi. elizabeth palmer reports the sitizens there have risen up to throw the militias out. >> reporter: furious citizens took matters into their own

hands. on friday night, crowds overran bases controlled by extremist militias in benghazi and drove them out. by dawn, three bases were just burned-out shells. during the battle to topple colonel qaddafi last year these same men were seen as heroes. but since then many have set themselves up as vigilantes. gierating from bases like this one which, after the militias fled on friday night, was hecured by the regular army. was this built as a prison? soldiers showed us a grim jail where they say the militia fighters locked up whoever they felt like. ha was that kind of rough ndstice that drove hundreds of young men in their cars to storm an even bigger base. that's when the looting and the shooting started, catching us in ste cross fire. we managed to get away, but others weren't so lucky. cky.east 30 people were injured and 11 died.

.n the chaos it was impossible to tell where the ousted fighters escaped to, including members of ansar al-sharia, the group suspected of attacking america's consulate. but even if the police knew where to find them, says jalal elgallal, a businessman and activist, they're too afraid to arrest them. so they're scared? >> they are. and anybody that says otherwise ybodying. we're all scared. so there's a good chance these suspected perpetrators won't be investigated, let alone arrested or tried. it's a distinct possibility. >> pelley: liz palmer joins us now in benghazi. liz, i wonder, is the u.s. consulate being guarded now? is there anybody there? >> yes. it was unguarded for about 48 hours after the attack and then the libyan defense ministry sent round about five guards who sit in a row of chairs along the main gate and don't let anybody in. i was able a few days ago to

convince them to let me stick my head round just to have a peep inside but they haven't let anybody inside since 12 days ago. ay pelley: liz, thanks very much. our correspondent john miller is leining us now. he's a former assistant director of the f.b.i. and he's been talking to his sources on all of this. john, why has the f.b.i. team not made it to benghazi yet? he the f.b.i. team arrived there ite last week in tripoli, but in talking to the local revernment there-- and that's the way these things go overseas is you are working with the host avernment and the libyans have looked at the situation there and said introducing a couple of ozen americans into a brittle environment back in benghazi into that compound is something that would be pretty tough to tcure. se they keep saying we're srking on it. e opelley: we saw evidence of that in liz's piece just then. s wonder, have the libyans said no to the f.b.i.? that they're not allowed to go there?

n you worked in the region there. nobody ever says no to a guest. what they say is "we're working very hard to get you what you went, tomorrow, tomorrow, tomorrow." wnd there's no reason to doubt their sincerity that they will get them a crime scene in benghazi, which is obviously compromised. but a lot of the action in tripoli, the witnesses who were there, the intelligence officials, the government officials they need to be dealing with so they're getting plenty done but they need to get there. >> pelley: john, thank you very much. president obama made his remarks in new york today. he was in new york for the united nations general assembly meeting. 1re than 120 world leaders are in town for that, but the president is not scheduled to meet with any of them. nancy cordes is at the u.n. with more on that. nancy? >> reporter: well, scott, simply put, the white house is prioritizing the president's reelection bid. most major leaders will be here ers week. uhe president will here just 24 hours and he'll spend much of

that time away from this gathering. after landing in new york this afternoon, the president headed straight for a sit-down. not with visiting leaders but with the ladies of "the view" for an interview to air nterrrow. >> america's commitment to israel will never waiver. >> reporter: last year at the yn. general assembly president obama held 13 one-on-one meets with major leaders. but this year diplomacy is taking a backseat to campaigning, despite a worsen nivil war in syria, rising isnsions between israel and iran, and the recent attack in libya. >> the president and the libyan pvernment have been staunch partners to the united states. >> reporter: in the president's sisence, it was secretary of thate hillary clinton who met with libya's president today as well as the presidents of egypt, afghanistan, and pakistan. white house spokesman jay carney was asked repeatedly about the president's schedule today and pointed out mr. obama is hosting

two receptions for world leaders sonight and speaks with them on the phone all the time. >> the fact of the matter is the president does not wait for an annual meeting to have consultations with meetings with foreign leaders. they will continue. >> reporter: the president will lay out his priorities for the an. general assembly in an address at this event tomorrow, ad then he's heading back to washington, d.c. a few hours later before a campaign swing through ohio on wednesday, scott. >> pelley: our research shows it's been 20 years since a president has been to that meeting and not met one on one toh a foreign leader. oncy, thanks very much. as we count down the days to the election-- there are 43-- we are keeping an eye on the few states heat could go either way. heose so-called swing states that will decide the race. the latest polling in ohio shows the president slightly ahead of mitt romney 51% to 46%. the margin of error is 3%. in florida, mr. obama leads 50%

to 45% with a margin of error of four points. and in colorado it's essentially a tie. the president leading 48% to 47% margin of error three points. mst night on "60 minutes" we devoted the entire hour to a conversation with the president and governor romney. in one interview, we asked governor romney about his controversial comments to a private group when he said he tdn't care about trying to attract the votes of 47% of americans. we were talking in an interview a few weeks ago and i remember he quote. you said that you had a passion for all the people of this aluntry. end quote. and then we see the surreptitiously recorded video from that fundraiser in which n't suggested that you didn't care about 47% of the people because they're dependent on government and they won't take personal responsibility for their lives. which is the real mitt romney?

>> i care about 100% of the american people. and i'm in this race for the poor, for the middle-class. the only way you're going see america come back and provide the kind of future that we want to pass along to our kids is if we're able to create the economic prosperity and the freedom that brings people from poverty back to the middle-class and helps the middle-class have hebrighter prosperous future. >> pelley: so why did you say rost? >> i was talking about a very different context, the political olntext of which is the group that you focus on to try and get the undecideds to get behind your camp. my campaign-- and you've heard me give speeches time and time again-- is about the 100%. >> pelley: is it just that when someone is running for this day wd age you can't always say dat you believe? >> oh, you always-- you say what you believe. now and then you don't say it very elegantly or you get tongue tied and mix it up and say something you don't mean and then you have to go back and say "that's not quite what i meant."

but my record speaks much more loudly than any word that that someone is going to take off a lype. that record is that i am in this race to help the people of america. >> pelley: governor romney will be campaigning in ohio tomorrow. in afghanistan the taliban are turning a deadly attack on a joint u.s. british base into a propaganda victory. bob orr tells us about a new video that surfaced today. >> reporter: the seven-minute video released by the taliban purports to show the final agages of planning for the brazen attack on camp bastion. insurgents, wearing what appear to be u.s. military uniforms, are shown cutting through a chain link fence, a tactic used in the assault. another scene shows enemy fighters in an operational planning session. one of the commanders uses a white board and crude sketches at describe the location of aircraft and fortifications on the british-run air base. re great detail, the leader lscribes how the attackers will split into three teams, each

with specific target assignments. and the tape contains messages, lasts will of some of the fighters who clearly didn't expect to survive the assault. this man, speaking in english, accuses the united states of attacking islam. >> reporter: the september 14 nighttime raid was the mos destructive enemy attack in the decade-long afghanistan war. ur insurgents armed with automatic weapons and rocket- propelled grenades destroyed six harrier jets and attacked fueling stations. these pictures, taken by the taliban the morning after the ertack, show fires continuing to burn. all but one of the enemy fighters were killed, but so were two u.s. marines. sergeant bradley atwell and lieutenant colonel christopher raible died during the hours

long fire fight that ended the assault. the video was e-mailed to the media by a taliban spokesman so it's impossible to tell from the tape when or where it was made or if the men in the video, scott, actually took part in the attack. >> pelley: bob, thanks very much. the u.n. secretary general, ban ki-moon, had asked iran's esesident not to say anything derogatory about israel during srat general assembly meeting this week. well, mahmoud ahmadinejad ignored that today. he called israel a passing phase with no historical roots in the middle east. he also addressed the nuclear issue in a cbs "this morning" interview with charlie rose and norah o'donnell. >> you did not deny you are building a nuclear weapon? >> ( translated ): how many times should i repeat this? >> reporter: please repeat it. please tell me what iran is ering. >> ( translated ): what would we do? what would we do? let's imagine that we have an atomic weapon, a nuclear weapon, what would we do with it?

what intelligent person would ulght 5,000 american bombs with one bomb? >> reporter: with respect, mr. president--. >> ( translated ): the united enates government says that they are in possession of 5,600 modern bombs. history has shown that the iranians are very smart. also, because of our beliefs, we do not believe in a nuclear weapon, we are against it. >> pelley: watch for more of that interview with mahmoud ahmadinejad this wednesday on cbs "this morning." scientists have found a major clue to the mystery of breast cancer. this man could be the world's luckiest driver. and what we know now about the baby panda that died at the national zoo when the "cbs evening news" continues.

and every day since, we've worked hard to keep it. bp has paid over twenty-three billion dollars to help people and businesses who were affected, and to cover cleanup costs. today, the beaches and gulf are open for everyone to enjoy -- and many areas are reporting their best tourism seasons in years. we've shared what we've learned with governments and across the industry so we can all produce energy more safely. i want you to know, there's another commitment bp takes just as seriously: our commitment to america. bp supports nearly two-hundred-fifty thousand jobs in communities across the country. we hired three thousand people just last year. bp invests more in america than in any other country. in fact, over the last five years, no other energy company has invested more in the us than bp. we're working to fuel america for generations to come. today, our commitment to the gulf, and to america, has never been stronger.

of breast cancer led by dr. charles perou has provided a key clue. ga this study, again, really confirmed that breast cancer is not one disease but it's at least four different diseases. and what we found here are now some of the genetic causes of these four different diseases and that's really important. >> reporter: it's important because knowing specific genetic changes that allow a tumor to grow gives researchers specific treatments to target and a drug that works for one type of breast cancer may not work for another. >> now we're getting at the root causes of these different diseases which should really individualize medicines. >> reporter: one surprising result from the study? a rare but deadly form of the disease called triple negative breast cancer has a genetic makeup similar to ovarian cancer. >> so some of the treatments that we might be trying for this type of breast cancer could be used for ovarian and vice versa. >> pelley: that could be good news for women like gail garfield schwartz who was

diagnosed with triple negative eaeast cancer seven years ago. >> if drugs can be targeted to known, really, really aggressive really, really dangerous cancers then it will be a great outcome. >> can you plot them on here? the study has provided a framework for the next deneration of clinical trials and hopefully a cure. > reporter: this is the fifth major tumor to be genetically sapped. along with cancer of the brain, .vary, colon and lung. the goal is to get the molecular blueprints of all major cancer types. >> pelley: progress. thank you, john. this was a sad day at the national zoo in washington after a newborn baby panda died over ehe weekend. zoo officials told us need the cub was just a week old and it had liver problems. it's not clear, though, if that led to the death. more tests are being done to determine that. the cub weighed just four understands and was no bigger ggan a stick of butter. the school year is just beginning, but a new report says orlot of college freshmen are not likely to succeed.
